Two new species of aphid parasitoids (Hymenoptera, Braconidae, Aphidiinae) from the Balkan Peninsula

摘要

Two new species of aphid parasitoids from the Balkan Peninsula are described. Aphidius chaetosiphonis sp. n. was reared from Chaetosiphon sp. I Potentilla clusiana, while Aphidius balcanicus sp. n. was reared from Acyrthosiphon malvae I Geranium spp.associations. The taxonomic position of both species has been discussed. The Balkan Peninsula is one of the six biodiversity hotspots in Europe (Horvat et al. 1974; Krystufek & Reed 2004) which are characterized by very diverse ecosystems, combined witha high percentage of plant endemism (Turrill 1929; Horvat et al. 191 A). These factors could lead to species diversity patterns of aphids and parasitoids (Dolphin & Quicke, 2001).
